Well, I run 2.3.50 on Abit BP6 with two Celerons and it had been fairly
stable for me. .. So I doubt it is "smp bug" as title imples.
Some datapoints.
- It looks for me kind of like overheading cpu. Thus
- make sure you are not overclocking anything
- make sure you got decent fans and working fan on each cpu.
- consider using silcon pasta.
- check temperature of each cpu in bios, should be 40'C or
less (over 50 everything usually goes to hell)
- if you want to use ATA/66 you need support for it.
Kernels 2.3.x have it. I think 2.3.50 is a good example here.
Some 2.2.x kerneles *might* have it, but I'm not sure which
The one shipped with redhat 6.1 for sure does not have it.
- for us to help you best you need to run the ops thru 'ksymops'
script. it is in /usr/src/linux/kernel/scripts/ksymops
- for easier catching of panic msg you might want to consider
using serial console to catch all output (see
linux/Documentation/serial-console.txt)
